Monsters? help!

My boyfriend is like addicted to caffeine and monsters. As in he drinks 3-5 a day. Lately he's been feeling like he's going to die... Lightheaded.. And such. So I made him stop drinking. Today he drank one... But he feels extremely sick.
And I'm just...

really worried about him.
How can I help him stop his cravings and get betterr?

More than likely it is some type of withdraw symptoms. The ingredients that give energy drinks energy, also increase the heart rate and increases w/ each drink ingested. The lightheadedness, nausea, and sick feeling should go away in a day or two, BUT---if he were to develop chest pains w/ nausea and numbness in the left arm, extreme heart rate fluctuations w/ the pulse feeling as if it is fluttering (palpations) or more lightheadedness he should see a Dr to examine him. Explain just as you did here as to what was going on w/ the energy drinks. They can treat him properly after examining him.
Warnings say to not to exceed 4 of these drinks per day.

Take him to a doctot. This sounds worse than I thought. Now one can has the caffiene equivalent of 125 cups of coffee. Let's say his average is four a day. 4X125=500. Thats the caffeine equivalent of 500 cups of coffee.

*** Oh yeah! KiDnEy StOnEs HeRe We CoMe!!!***

get him help right away.

One can being the equivalent of 125 cups of coffee is not possible---one can would cause caffeine overdose. Maybe you heard 125 mg per can---that makes more sense.

No one would be capable of drinking the equivalent of 125 CUPS of coffee in one sitting without becoming seriously ill or dying. (;

Monster is 160 mg of caffeine per 16 oz. can. 10 mg/oz
Brewed coffee has 107 mg of caffeine per 8 oz. cup 13.4 mg/oz
Drip coffee has 145 mg of caffeine per 8 oz. cup 18.1 mg/oz
Coffee is stronger per ounce.

This is not an area that I have much knowledge in, however it may be just his general diet. Monster has a lot of sugar and that might be giving his body a lot of energy without balanced nutrition. I know that if I snack on too many sweets (Oreo cookies are my weakness!!), my stomach feels real upset. Like almost vomiting. I have to go to some good protein (cheese, peanut butter sandwich, chicken, or steak) to calm it down. Or high quality bread. Nothing sweet or salty. Or for that matter, any 'comfort' food.

If he is feeling REALLY bad, yes, by all means encourage him to see a doctor!!

The both of you, take care, and
Good Luck!!

Thanks you guys
He hasn't drank a monster in 6 days.
Andd I'm really really proud of him (:
